The microbial quality of the working environment was assessed in winter in air-conditioned office buildings in Warsaw. The average indoor concentrations of bacterial and fungal aerosols were low (<10³ cfu·m⁻³), below Polish proposals for threshold limit values in public service buildings. Even during cold months, if the air-conditioning system works properly, people remain the main source of bacterial aerosol in offices, whereas infiltration of outdoor air remains a major mechanism responsible for their fungal contamination. An analysis of the bioaerosol size distribution showed that microbial propagules that reach both the upper and lower respiratory tract may evoke numerous adverse health effects from irritation and asthmatic reactions to allergic inflammation. A comparative analysis of viable and total airborne microbial counts showed that viable micro-organisms accounted for up to 0.3% of the total number of microbial propagules. Hence, a comprehensive hygienic assessment of office workplaces should include an efficient control of both these elements.
研究评估了冬季华沙空调办公建筑工作环境的微生物质量。细菌和真菌气溶胶的室内平均浓度较低（<10³ cfu·m⁻³），低于波兰公共服务建筑建议的阈值限值。即使在寒冷的月份，如果空调系统运行正常，人仍然是办公室空气中细菌气溶胶的主要来源，而室外空气的渗透仍然是其真菌污染的主要机制。对生物气溶胶粒径分布的分析表明，到达上呼吸道和下呼吸道的微生物繁殖体可能会引起许多不良健康影响，从刺激和哮喘反应到过敏炎症。对可培养和总空气微生物计数的比较分析表明，可培养微生物占微生物繁殖体总数的 0.3%。因此，办公场所的综合卫生评估应包括对这两个因素的有效控制。
